METHODS, APPLICATIONS, AND LIMITS OF ASSESSING RESIDENCE TIME DISTRIBUTIONS OF SOLUTES IN STREAMS

Streams are viewed as both integrators of upslope watershed processes and as open systems that are intimately connected to alluvial and deeper aquifers. Hence, measurements of spatial and temporal patterns of stream solutes and hydrology can provide characteristics (i.e., mean residence times, median transport times, etc.) of residence time distributions (RTDs) of water and solutes in both stream channels and the broader watershed. Several new methods for estimating RTDs and their properties have been developed and applied in streams in the past decade. We will compare and contrast such methods for conducting, analyzing and modeling stream tracer experiments. Although all of these methods have common practical limitations related to tracer properties or measurement techniques, the ability to more accurately characterize RTDs continues to refine our understanding of associated biogeochemical cycling in streams and watersheds.
